소음 측정기

Sound Level Meter

소음 측정기는 사람의 귀와 같은 방식으로 소리에 반응할 수 있게 설계된 제품입니다. 소음 측정기는 산업 환경에서 보건, 산업안전, 품질관리 등 여러 분야에서 사용 하고 있기 때문에 음압 레벨을 객관적으로 측정 해야 합니다. 당사 소음 측정기는 국제 표준에 정의된 클래스1의 정확도를 보유하고 있으며, 쉽고 간편하게 이용할 수 있도록 설계되었습니다.

Application

· 소음 및 소음원 식별 · 제품 소음 식별
· 작업 현장 소음 측정, 평가, OHS 평가 · 환경 소음, 진동 준수 확인
· 환경 위생 및 안전성 테스트 및 확인 · 교육 환경의 소음 테스트
· 중공업 및 경공업 소음 테스트 · 의료 환경 테스트
· 안전성 테스트
